Do NOT use sealants containing acetate or silicone, which can cause damage to plastic parts. Anti-fouling Where local regulations allow, it is recommended that you coat your transducer using a water-based anti-fouling paint.
Page 20
The anti-fouling paint should be applied in a thin and even coat covering all externally exposed transducer surfaces. You should clean your transducer regularly and re-apply anti-fouling paint every 6 months, or sooner depending on how rapidly organic growth builds up. Refer to 6.2 Transducer cleaning for cleaning guidance.

Warning: Transducer operation Only test and operate the transducer in the water. Do NOT operate out of water as overheating may occur.
3.3 Selecting a location Warnings and cautions Important: Before proceeding, ensure that you have read and understood the warnings and cautions provided in the Chapter 1 Important information section of this document. Location requirements Follow the guidelines below when selecting a location for your single transducer or split-pair transducers.
Page 23
• The transducers should be installed away from any protrusions such as other transducers, steps, ribs, strakes, or rows of rivets. • Transducers should be installed in a location where no load will be applied to the transducers during, launching, lifting, trailering and storage of the boat. •...

36. Remove any excess marine-grade sealant. 37. Ensure that the marine-grade sealant has fully cured Refer to the sealant manufacturer’s instructions for curing times. 38. Unless local environmental regulations prohibit, apply a water based anti-fouling paint to the bottom face of the transducer, ensuring all of the externally exposed transducer surfaces are coated and the paint overlaps onto the hull.

The anti-fouling paint should be applied in a thin and even coat covering all externally exposed transducer surfaces. You should clean your transducer regularly and re-apply anti-fouling paint every 6 months, or sooner depending on how rapidly organic growth builds up. Refer to 6.2 Transducer cleaning for cleaning guidance.
• Unless otherwise stated only use cables supplied by Raymarine. • Where it is necessary to use non-Raymarine cables, ensure that they are of correct quality and gauge for their intended purpose. (e.g.: longer power cable runs may require larger wire gauges to minimize voltage drop along the run).
4.2 Cable routing Cable routing requirements for the transducer cable. Important: To avoid interference, the cable must be routed as far away from VHF radio antenna devices and cables as possible. • Check that the cable is long enough to reach the display it will be connected to. Optional extension cables are available, if required.
4.3 Making connections Follow the steps below to connect the cable(s) to your product. 1. Ensure that the vessel's power supply is switched off. 2. Ensure that the device being connected to the unit has been installed in accordance with the installation instructions supplied with that device.

6.1 Routine checks The following periodic checks should be made: • Examine cables for signs of damage, such as chafing, cuts or nicks. • Check that the cable connectors are firmly attached and that their locking mechanisms are properly engaged. Note: Cable checks should be carried out with the power supply switched off.
6.2 Transducer cleaning You must clean your transducer regularly to remove organic growth. Organic growth can build up quickly on the bottom face of your transducer; this can impact transducer performance in a matter of weeks. Important: • When cleaning growth from an anti-fouled transducer, take care not to let paint dust and other debris enter the water, as this can have an impact on aquatic life.
6.3 Re-applying anti-fouling paint If you have applied anti-fouling paint to your transducer, it is important to re-apply it at least every 6 months, to maintain effectiveness. Follow the instructions below to re-apply anti-fouling paint. Important: • Following environmental best practice, preparation and re-application of the anti-fouling paint should be performed using suitable washdown facilities, which ensures paint particles do not enter the water and impact aquatic life.
